Making edibles by hand — pan on the stove, thermometer in hand, hoping you don’t scorch the butter — works, but it’s inconsistent, smells up the house, and loses potency through imprecise temperature control. A dedicated cannabutter machine solves all three problems. The question is which one actually delivers.
I’ve run batches through three of the most popular machines using the same material from the same harvest. Here’s the honest breakdown.
No products found.
- The Ardent FX is the best all-in-one for home growers who want the simplest workflow: decarboxylate AND infuse in one device, no grinding required
- The LEVO II produces the cleanest, most refined infusion with the least particulate — best for precision oil work
- The Magical Butter MB2e wins on versatility and batch size at the lowest price point of the three
- All three require properly decarboxylated material for maximum potency — only the Ardent FX handles decarb internally
- Potency is determined primarily by your material and decarboxylation accuracy, not the machine brand
Why Use a Cannabutter Machine at All?
Decarboxylation — converting THCA to THC through precise heat application — is the single most potency-sensitive step in making edibles. Stove-top methods lose significant potency to temperature spikes and inconsistency. A dedicated machine maintains precise temperature throughout the infusion cycle, resulting in more consistent, more potent results batch to batch.
According to a comparison review by The Green Treasure (The Green Treasure), the three major consumer-grade infusion machines each take a different approach to the same problem.
LEVO II: Best for Precision Oil Infusions
LEVO II
- Price: $250–$300
- Capacity: Up to 16 oz oil / 1 cup butter
- Internal decarboxylation: Yes (separate cycle before infusion)
- Best for: Precision herb oil, refined butter infusions, minimal particulate
The LEVO II uses a pod system where dried herb is loaded into a perforated metal pod and submerged in the oil or butter. This design means zero plant material ends up in your final product — no straining required. The companion app allows saved presets and potency estimates.
Pros: Cleanest output of the three; excellent companion app; compact footprint; very easy to clean.
Cons: Smaller capacity than Magical Butter; decarb and infusion are separate two-step cycles; higher price relative to batch size.
My experience with the LEVO II: The output is noticeably cleaner than my stove-top method. When I use it for olive or avocado oil, the clarity difference is immediately visible — you’d never know the oil was infused until you eat it. For butter-heavy recipes where you want a neutral taste, this machine is hard to beat.
Magical Butter MB2e: Best for Large Batches and Versatility
Magical Butter MB2e
- Price: $175–$200
- Capacity: 2–5 cups (much larger than competitors)
- Internal decarboxylation: No (requires external decarb first)
- Best for: Large batch production, tinctures, multiple infusion types
The Magical Butter MB2e is the most versatile machine in this comparison. It handles butter, oil, tincture, and lotion in batches of 2–5 cups. A heating element and integrated blending blade mix continuously throughout the infusion cycle.
Pros: Largest batch capacity; most versatile for butter, oil, tincture, lotion, and glycerin; lowest price; simple push-button operation.
Cons: No internal decarboxylation; integrated blade creates more particulate requiring straining; more cleanup time; louder operation.
Ardent FX: Best All-in-One for Simplicity
Ardent FX ★ Redd’s Pick
- Price: $350–$380
- Capacity: Up to 5 cups infusion
- Internal decarboxylation: Yes — the signature feature
- Best for: Home growers who want the absolute simplest workflow
The Ardent FX is the only machine in this comparison that decarboxylates AND infuses in the same unit. Load your flower, run the decarb cycle, then add your butter or oil and run the infusion cycle. No oven, no separate step. Works with whole flower — no grinding required.
Pros: True all-in-one; no grinding needed; clean modern design with carrying case; cleanest potency-to-investment ratio.
Cons: Most expensive; smaller oil capacity than Magical Butter; longer total cycle time.
Which Machine Should You Buy?
Buy the Ardent FX if: You want the simplest possible workflow and don’t want to own a separate decarb device. The all-in-one approach removes the biggest failure point in edibles (improper decarb) and works with whole flower.
Buy the LEVO II if: Output quality and cleanliness matter most. If you’re making infused cooking oils for everyday cooking and want professional-looking output with no plant material, the LEVO II’s pod system is unmatched.
Buy the Magical Butter MB2e if: You’re making large batches or want flexibility to make tinctures, infused lotions, and multiple product types at the lowest entry price. Just buy an Ardent Nova for decarb separately ($100) or use the oven method.
The dirty secret of cannabutter machines: Your decarboxylation accuracy matters far more than which machine you pick. The Ardent FX wins for home growers not because of its infusion quality but because its decarb cycle is precisely engineered — it’s the machine where the highest percentage of THCA converts to THC before infusion begins.
How to Get Maximum Potency from Any Machine
- Decarboxylate properly — 240°F / 115°C for 40 minutes for THC, or 220°F for 60 minutes for a more terpene-preserving decarb
- Don’t overheat during infusion — Stay below 200°F (93°C); higher temps burn off terpenes and can degrade cannabinoids
- Use quality material — Trim works fine for cannabutter; use top flower for smoking and trim for edibles
- Grind medium — Too fine creates excessive particulate and bitter taste; too coarse reduces extraction
Frequently Asked Questions
Can I use fresh frozen cannabis in a cannabutter machine?
No — fresh frozen material contains too much water content for infusion machines. Always use properly dried and cured material, or trim that has been fully dried. Using wet material produces a weak, watery infusion.
How much cannabis should I use per cup of butter?
A common starting ratio is 7–10 grams per cup of butter for moderate potency. Start lower (5 grams) if you’re new to edibles and adjust up in subsequent batches. Precise dosing requires knowing the approximate THC% of your starting material.
Do all machines produce the same potency output?
In theory yes — if starting material quality and decarb accuracy are equal. In practice, the Ardent FX’s integrated decarb gives it a slight edge for most home users because decarb is where potency is most commonly lost.
Is the Magical Butter machine worth the savings vs. LEVO?
Yes, for most people — especially if you have a reliable decarb setup. The $75–$125 savings buys a lot of material. The LEVO II is worth the premium if output cleanliness and kitchen aesthetics matter to you.
